The study of the Federal District reveals an original form of migrant insertion, or rather, spatial segregation, reflecting social inequalities, leading to a polynuclearization. This phenomenon translates to the creation of urban neighborhoods in the periphery, which are both disconnected and entirely dependent on the center. Since the construction of the new capital, isolated in the Goias state, migrants have flowed into the Federal District. They, however, have not been integrated into the Master Plan itself, but rather displaced even further to the periphery, creating difficulties for the receiving municipalities that lack the resources to accommodate them.
**The Center of Hope, its Satellites, and its Peripheries**: The Brasilia plan was designed to accommodate 500,000 inhabitants. By 1970, ten years after the inauguration of the new capital, the population fixed by the project had already been reached and concentrated no longer in the initial Master Plan. Today, more than 3/4 of "Brasilia" residents live in a satellite city. The first arrivals, workers on the construction of the city, settled in makeshift camps around the city. Under the pressure of migrations of functionaries and immediate real estate speculation deviating from the original egalitarian principles, access to the "legally" Master Plan became quickly impossible for their income. Occupying the land illegally and damaging the "harmony" of the architecture, these shantytowns could not remain at the gates of Brasilia. Instead of modifying the urbanization plan, they created satellite cities to move poor populations away from the center, creating a "sanitary vacuum". The builders of this dream, mostly illiterate, only have access to rare, poorly paid, subordinate, and unstable jobs in the informal sector, building, administration, and services, and the household sector.
